    • Performance Comparison: 2020 Chevrolet Corvette Stingray (3LT Z51) vs. 2020 Mustang GT500 and GT500 CFTP

      It certainly is interesting to see the Mustang taking on the Corvette. Especially considering the GT500 is going about its business with huge weight and big power while the Corvette is now about balance and efficiency.


      The C8 Corvette is not light by any means at 3587 pounds but the 39% front to 61% rear weight balance helps it put power down and make use of where that 6.2 liter LT2 V8 is positioned.

      On the other hand, the GT500 has most of its weight up front with 56% of its 4149 pound curb weight on the nose. The CFTP (Carbon Fiber Track Pack) option drops the curb weight to 4054 pounds thanks largely in part to the carbon fiber wheels and rear seat delete.

      The Corvette is lighter and better balanced but making much less power with 495 naturally aspirated horses compared to the GT500 and its (underrated) 760 horsepower blown 5.2 liter Predator V8.

      Despite the power disparity MotorTrend gets the Corvette through the 1/4 mile quicker with an 11.1 @ 123.2 pass. Traction tells the story as the GT500 CFTP manages an 11.3 @ 131.6. That trap speed is easily enough to go deep into the 10's.

      As a matter of fact, it is so much more power that the GT500 CFTP is over four seconds quicker at VIR (Virginia International Raceway). The standard GT500 was over a second quicker as well. For 4000+ pound behemoths, that is impessive.

      Clearly the Mustang is using brute force to accomplish the goal. For once in recent memory, the Corvette is more about finesse and precision handling than power in a performance comparison.

      Two very different cars but both exciting in their own way. Not to mention, they offer value that nobody else in the world can beat.

      MotorTrend seems to feel the same way:

      The incredible performance capability of the new Shelby (especially with the Carbon Fiber Track package) moves the Mustang into the supercar realm, it pleases me to claim. Both Shelby models provide such thrills that they represent good value even at these prices—driving with confidence-inspiring and consistent speed that is rare to find at any price.

      So, to the numbers: Lap times for the C8 Z51 and the standard GT500 were quite comparable, though achieved in different ways. The Shelby evaporates the straights; the C8 carves the corners.

      The Shelby carries the load of your family, so in spite of its fantastic, predictable balance, the Corvette can leave it in the twisties, driven precisely.

      Once we tried the GT500 equipped with the Carbon Fiber Track package, however, it was all over for the street 'Vette. The CFTP Shelby is magic on the racetrack, wearing R-compound Sport Cup 2s, carbon wheels, lower and firmer springs/bars/shocks, a proper wing and hell-yes-they-work aero fitments, and much more. Fire it up, and the Shelby is long gone in a blaze of glory.

      So here's the greatest difference between these fantastical motorcars. Shelby: raging, proficient power. C8 Corvette: precision, potential, and style. The price, similar. The choice, yours. The pleasure, ecstatic.

        Or the GT500 drivetrain in a Ford GT.

        Wish the track test had been on the longer VIR course so we could get a rough compare to the Lightning Lap cars. Both look to be crazy fast. Probably mid to low 2:40s.

        Actually I’m really glad they ran these on the Full course.

        The “Lightning Laps” are the only times you ever see cars on the Grand Course layout. Almost all races and HPDE sessions take place on Full.

        So it’s nice to see times like this because they’re comparable in the real world. To real world cars, drivers and times.

        Good points, but I appreciate the Lightning Lap because it’s a (relatively) controlled environment so the compares are interesting.
